Serialize and validate according to `ServiceProviderConfig`

[azmeuk]

Passing ServiceProviderConfig to the serialization and validation context would allow to check for additional things.

For example:

• if changePassword is not supported by a server, then it could raise a ValidationError when used in a RESOURCE_REPLACEMENT_QUERY_CONTEXT for instance.
• if etag is not supported, then response contexts should reject payloads containing etags.
• if filter or sort are not supported, then they should not be passed when building SearchRequest objects.
